CHARGED PARTICLE MULTIDETECTOR

摘要

A charged particle multidetector comprising a plurality of electrodes supported on a monolithic substrate. An amplifier is provided in respect of each electrode and circuits are provided for detecting the arrival of a charged particle at any one electrode. Counters are provided in respect of each electrode and the contents of the counters are incremented in response to each detection of the arrival of a charged particle at the respective electrode. The counters and associated circuitry providing inputs to the counters are all mounted on the same monolithic substrate as the electrodes. The accumulated content of each counter is read out periodically to appropriate signal processing devices.
